IMPROVEMENT IN TRACTION-ENGINES.

Specification forming part of Letters Patent No. 129,437, dated July 16, 1872.

SPECIFICATION.

Nature and Object of the Invention.

My invention relates to the mode of adhesion to the surface of the road by means of the use of feetcombined with the wheel or axle; also, a friction-roller and clutch, hereinafter more fully described.

Description of the Accompanying Drawing.

Figure Us a side elevation of the pulling movements. Fig. II is a side elevation of the friction movements of the same. Fig. III is an elevation, showing a vertical section of both m ovements.

General Description.

A, Fig. I, is the support, to which the movements are attached and which serve as a substitute for a wagon. B is awheel fastened'on axle C. This wheel B has a crank-pin, D, which drives rod E and gives motion, lever F with its foot-piece G intended to rest on the ground. This lever F swings on pin H of the pendulum K, which pendulum has it fulcrum at I. If wheel B revolves the cam M receives pin L and raises foot G from the ground, and roller 0, Fig. III, on stationary rod N. When roller 0 reaches the end of the rod N foot G drops to the ground, and by means of crank pull or push on dogs 0 0, Figs. II and III, which are swinging in arms i i and h h, which arms are movable on axle 0. By this motion the dogs 0 c are forced against grooved roller 61 in such a manner as to prevent the dogs 0 efrom slipping, and causes axle O to rotate in a continuous manner. To allow roller 01 to turn in both directions the position of the dogs 0 e are changed, which is effected by two projections or cranks, e e, Fig. III, and the forked pieces ff, by means of an eccentric attached to lever l. Arched stand h is intended to hold lever l in its proper place.

Claims.

I claim 1. The motion produced by the combination of devices described. whereby the feet are brought in contact with the surface of the road, propel the wagon, and are raised and moved into position.

2. The pin D, rod E, lever F, pendulum K, cam M, pin L, stationary rod N, roller 0, and foot G, arranged and operating in the manner and for the purpose substantially as herein shown and described, in combination with the friction-roller d and clutches or dogs 0 c with reversing-lever l, and eccentric g and forked shafts ff, and arms h h, whereby the motion may be reversed or the devices thrown out of gear altogether.

3. The combination of devices which pro ducesadouble-actingreversiblefriction-clutch, as and for the purpose set forth.
